8/11/2023 0 Comments Delta meander river![]() ![]() There is four major type of estuaries which are drowned river valley estuary, bar-built estuary, fjord estuary and tectonic estuary. While an estuary is a semi-enclosed body of water, where river meets the ocean, the delta is a low-lying plain, formed by the accumulation of alluvium. Delta is good for agricultural activities, while fishing activities are suitable in estuary regions.As against, the area nearby estuary is not fertile in nature. The land of the delta is fertile in nature.In contrast, the delta is formed when the rivers witness low tides. Rivers that encounter high tides are more likely to form estuary.Conversely, Delta is a triangular land at the river mouth travelled across by its distributaries. The estuary is like funnel-shaped, the mouth of a river from where the tides move in and out.In India, rivers like Narmada and Tapi forms estuary, whereas Delta is formed by the Mahanadi, Godavari, Krishna, Cauvery, Ganga and Brahmaputra rivers.On the other hand, the delta is defined as the wetlands, that is formed when a fast moving river joins a slow-moving water body, and thus empty the sediments at its mouth. It is a place where the river meets the sea. By estuary, we mean a semi-enclosed waterbody, comprising of brackish water. ![]() The difference between estuary and delta are discussed in the points given below: Key Differences Between Estuary and Delta subaqueous, subaerial, lower delta plain, upper delta plain. It occurs where the river joins a larger watercourse whose flow of water is slow and is not able to transport the supplied sediment and leaves it at the river mouth which results in the formation of the delta.ĭelta is build up by continuous deposition of sediments, which makes the water shallow, causing the landform to rise above the sea level. Definition of Deltaĭelta is defined as the landform, created out of deposition of sand, clay and slit, brought by the river, as the river enters another river, sea, ocean, lake, etc. In addition to this, the water level and salinity varies with tides. It may also be called as bay, lagoon and slough.ĭepending upon the location and climate, the size and shape of the estuary may differ. In short, it is an area where tides flow in and out, and the river becomes wider and slowly converges the sea. It is partially enclosed by land and contains brackish water, i.e. The estuary can be understood as the coastal waterbody of one or more rivers that links to the sea or ocean. Mahanadi, Godavari, Krishna, Cauvery, Ganga and Brahmaputra form delta. Content: Estuary Vs DeltaĮstuary refers to the waterbody, along the coast, that are formed when fresh water of river meets salt water of ocean.ĭelta connotes a landform that is formed by river-borne sediments deposited at the river mouth when it joins the sea. So, let’s take a read of this article to know more differences on these two. In short, the basic difference between estuary and delta is that the former is a tidal mouth of the river, where it meets the sea, whereas the latter is nothing but the wetland, formed as a result of the accumulation of sediments carried by the river when it joins a standing waterbody. ![]()
